Re: Increase in free energy in glycolysis

... and PFK1 making Fructose-1,6-Bisphosphate is made to overcome the activation energy of the subsequent step. I don't know what you understanding of biochemistry is and if that concept of free energy and activation energy needs to more thoroughly explained.

Re: Number of water molecules produced by cellular respiration

... now down to 12 -3 waters or 9 waters produced. 3 are still in excess of the equation but I am sure that those can be found by looking at better biochemistry resources where they show more details about the individual reactions occurring in the active sites of the enzymes.
